polyacrylamide low molecular weight in nepal

  • Biodegradation of low molecular weight

    2020-1-15 · The molecular weight was reduced from 1.6 × 10 6 to 6.45–7.42 × 10 5 Da for the low molecular weight PAM, while the high molecular weight PAM declined from 2.2 × 10 7 to 3.76–5.87 × 10 6 Da. The results showed that the amino hydrolysis of low molecular weight PAM is easier than that of the high molecular weight one, while the cleavage of its carbon chain is still difficult.
